SAMPLING TOOL.

- Application filed December 14,1925. Serial No, 75,481.

This invention relates to a sampling tool for use in obtaining oil samples from oil tanks or the like.

The object of the invention is'to provide a sampling device of this character which may be used to obtain a sample at any depth, which cannot stick or clog, which is easily adjusted, and which may be easily opened when it is desired to take the sample therefrom. i

A further object resides inv the provision of a sampling device of this character and having these advantages and which is of simple and durable construction, reliable '15 and effective in operation and easy and comparatively inexpensive to manufacture.

Other objects and advantages reside 1n certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being' had-to the accom- .panying drawings forming a part of thls specification, and in which:

FigureTl is a perspective View showing a sampling device constructed 1n accordance with the present invention,

Figure 6 is a similar view looking in the direction of the arrows 6-6 in Figure 3,

Figure 7 is a top plan View, V A

Figure 8 is a view in horizontal cross sec tion on the line 88 of Figure 2, and Figure 9 is a. .detail sectional view: on the line 99' of Figure 1.

Referring to the drawings it'will be seen that the "sampler constituting .the present inventionincludes a hollow body, designated generally at 1, and preferably 'made up ofa hollow cylinder2 of glass or the like protected by curved' guard plates 3 of metalwhich are held against the glass cylinder by end lates 4 and 5' secured to theguard plates 3 y screws 6. The guard plates have lugs 3 at their ends which abut the end pieces or heads 4 a.nd and with which the 3 screws 6 co-act.' Elastic packing rings 7 are interposed between the ends of the glass cylinder 2 and the end pieces or heads 4 and- 5 as illustrated to advantage in Figure-2. Both of the end pieces 4 and 5 have annular flanges, designated at 8 and 9, respectively, flanges 8 and 9 snugly fitting over the ends OfthecylinderS as also seen to advantage in Figure 2. The upper end piece or head 4 is provided with a large central opening 10. The lower end piece or head 5 is provided with a plurality of openings 11 having the approximate form of a sector. A closure is provided for the openings 11 and consists of a plate 12havi'ng a hub 13, closure elements or ribs 14 provided with beveled edges 15 and a peripheral ring 16 provided with outwardly extended inclined lugs 17' and 18. The hub 13, closure ribs 14, peripheral ring 16 and the lugs 17 and 18 are all preferably .cast or otherwise suitably formed integral.

The hub 13 of the closure is suitably fastened, as at 19, to a pivot shaft 20 rotatably fitted in an opening 21 provided therefor in the lower end iece or head 5.= At its upper end the shah: 20 provided with a flange 22 which is integral therewith or otherwise suitably fixed thereto. A torsional coil spring encircles the shaft 20 above the lower head 5 and has its lower end fastened, as at 24, to the plate 5 and its-upper end fastened, as at 26, to the flange 22 of the shaft 20. The spring 23 is not only tor- D0 sionally tensioned but is under compression to a slight extent so as to resiliently hold the closure plate 12 snugly up against the underside of the lower end plate or head 5 and also maintain this closure plate 12 in r such angular position that its ribs or closure elements 14 cover and close the openings 11.

The lugs 17 and 18 aiford a convenient means whereby the closure plate 12 may be turned against the tension of the spring 23 1 0 v to move the closure elements or ribs 14- out of registry with the openings 11, thereby o ening the lower .end of the sampler.

eans is provided for releasablyholding the closure plate in such open position and consists of a lock rod or holder rod 30 slidably fitted in guide openings provided therefor in lugs 31 on the end pieces 4 and 5.

The lower end of the lock rod 39 is beveled,

'as indicated at 32 (see Fig. 6) and this l0w- 119 er beveled end is engageable withthe lug 17 to hold the lug and the closure plate 12 in open position. The lock rod 30 is yieldably held in position to engage the lug 17 by means of an expa-nsible coil spring 33 e11 circling the upper portion of the lock rod 30 and abutting the underside of the lug 31- of the end piece or head 4 at one end and a cotter pin 34 carried by the lock rod 30 at its lower end.

In orderito trip or release the lock rod at any desirable distance above the bottom of the tank, a trip rod 35 is provided and is slida'bly fitted in a guide opening 36 provided in the lower end.' The upper end of the trip rod 35 carries a block 36 having a pair of arms 37 which have openings in which the lock rod 30 is slidably fitted. A spring catch or latch 38 is provided and has one end fastened, as by means of a screw 39,

to the block 36. The other end portion of the; spring latch or catch member 38 is disposed in between the arms 37 and by virtue of its inherent resiliency presses up against the lock rod 30. The lock rod 30 is provided at spaced intervals with notches 4.0 with which the catch 38 is selectively cooperable. The lower end of the trip rod 35 projects below the sampler and the extent to which it so projects may be regulated by sliding it along the lock rod and securing it in adjusted position thereon by engaging its latch 38 with the selective notch 40. When the trip rod strikes the bottom of the tank it moves the lock rod 30 upwardly a ainst the action of the coil spring 33 an disengages the lower end of the lock rod from the lug 17 thereby permitting the spring 23 to swing the closureplate 12- to closed position.

A bail, 50 is connected with the upper head or end piece 4 and has an eye 51 to facilitate its attachment to a lowering line chain or catch pole, said bail constituting with said chain or line means for lowering the sampling device. In the construction illustrated one arm of the bail 50 has a trunnion 52 which is engaged in a bearing 53 provided on the upper end piece 4. The other arm of the bail has an extension 54.

- provided with an opening 55 receiving the outturned upper end 56 of the lock rod. A cotter pin 57 prevents displacement of the outturned ends 56 of the lock rod 30 from the opening, 55 of the extension 54 of the bail. This arrangement permits the lowering line to be jerked to disengage the lock rod from the lug 17 and permit swinging of the closure plate 12 to closed position.

In the use of the device the closure plate 12 is swung to open position and is held in such position by the lock rod 30. The device is then lowered into the oil and the oil passes in through the openings 11 and out through the upper open end until the sampler is in the region where it is to take a sample. The closure plate is then closed by jerking the closure to closed :closure plate swings to closed position its lugs 18 are engaged with the screws 6 to hold the plate in such position.
